HOW TO PLAY

PLANKX is a third-person track arcade. Tiles tumble down five lanes. Catch them on the paddle, drop them into a 5x5 well, and nail lines of 3 or more matching colors. Game by @generaldeeez.

INSERT COIN

This cabinet is connected to Robinhood Chain Testnet 46630. It moves test tokens only: no mainnet token, cash, or real-money payout is enabled.

• A testnet coin is 1 USDG. The $PLANK button accepts $1 of testnet $PLANK within the on-chain safety band. 100 $PLANK is not $1.
• $PLANK / $1 - testnet insert, 4 on-chain credits. COLLECT COINS mints test USDG only.
• Keyboard 1 = $PLANK. Keyboard 2 = $1.
• The display caches your credit count locally; the contract is the source of truth.

4 credits per coin. PLAY launches the local game. At game over, posting a testnet score spends one on-chain credit; declining that wallet transaction posts no score and spends no on-chain credit.

GOAL

Match 3 or more tiles of the same field color:

• HORIZONTAL - across a row
• VERTICAL - up a column
• DIAGONAL - either diagonal

Colors: purple, orange, blue, green, white, pink. Several faces can share a color. The wave goal is printed at the top of the CRT (lines, horizontals, diagonals, verticals, or a score target).

CONTROLS

• LEFT / RIGHT or A / D or on-screen arrows - slide the paddle one lane at a time. Holds retarget with a short tick (~0.09s) so it still reaches lanes 0 and 4.
• Click or drag on the track - target the nearest of 5 lanes; the paddle slides there (does not teleport).
• DOWN / S / SPACE / DROP or a quick tap - drop the bottom caught tile into the well under the paddle.
• UP / W / TOSS or swipe up - toss the top caught tile back up the track.
• PLAY / Enter / tap the CRT - start a run. With no wallet connected this starts a FREE PLAY run.
• FREE - toggle free play by hand. A run settles the way it was played, so flipping it mid-run applies to the next one.
• P - pause / resume. ESC - pause, then ESC again quits to attract.

On a phone the on-screen deck under the CRT is the whole control set. Holding an arrow repeats.

FREE PLAY / MOBILE

You do not need a wallet to play. Press PLAY with nothing connected and the cabinet runs FREE PLAY: unlimited local runs on any browser, desktop or phone. Free play never touches the chain - no credit is spent, no score is posted, and the leaderboard is the local one on your device. A free run is marked FREE on the game-over card.

Mobile Safari and Chrome have no extensions, so no wallet is injected there and CONNECT has nothing to find. To use a wallet on a phone, open PLANKX inside your wallet app's own in-app browser (Robinhood Wallet, MetaMask, Rainbow, Trust). Connecting leaves free play and hands the cabinet back to coins, on-chain credits and the public scoreboard.

The paddle slides smoothly toward its target lane. Catch a tile when it is in the catch window and close to the paddle, including while sliding and on outer lanes 0 and 4.

THE WELL

The well is 5 columns x 5 rows. Tiles pack to the floor. Any column with fewer than 5 tiles accepts a drop. A full column refuses the drop. Fill the whole well with no matches and the game is over.

WAVES

Clear the printed goal to finish a wave. Speed and spawn rate climb. A short WAVE flash stays on the CRT. The game does not freeze for an ad. Completing a wave restores one drop, max 8.

DROPS / MISS

You start with 5 drops. Miss a tile past the paddle and you lose one. Zero drops is game over. Tossed tiles rejoin the track; they are not misses until they pass the paddle later.

The paddle holds up to 5 tiles. If it is full you cannot catch until you drop or toss.

SKILL WIN-BACK

Skill win-back is visual only. Clearing waves and hitting score marks can light up a testnet WIN-BACK message, but it is not a slot, a token transfer, or a payout.

SCORING

• Vertical line - 50 x wave
• Horizontal - 1,000 x wave
• Diagonal - 5,000 x wave
• Four-in-a-row x4. Five-in-a-row x10. Chains multiply.

Local high score saves on this machine. Testnet score posts are public, but they do not pay out.

LEADERBOARD

Without a wallet, the cabinet keeps a local top 10 by POINTS and visual win-back. With a wallet, it reads the public testnet board. Until a cabinet signer is configured, that board is self-reported and is never a payout oracle.

GAME OVER

Each loss rotates a roast on the CRT. Some of them send you to smoothbrain.app to make the crying-in-the-casino meme.

THE BIT

This is a skill cabinet. You pay to play. You get the ride, and maybe a prize worth less than you put in. That gap keeps the lights on. Said out loud on purpose. No burn.

The current testnet split is described on THE BIT: 1 USDG or $1 of testnet $PLANK, 4 credits, 10% House / 2.5% plank.love / 2.5% cups / 85% arcade reserve. No burn. No mystery juice. No score payout.

Not an investment. Not advice. Not an ATM. The well does not owe you a house. $PLANK, NFTs, and memecoins can go to zero while you're still smiling. If that bothers you, the door still works.

TESTNET ONLY

The wallet flow is limited to Robinhood Chain Testnet 46630 and explicitly refuses mainnet. It sends ordinary approve / insert / score transactions only when you confirm them in your wallet. It never asks for a seed phrase.

Plank is Plank. Opt in or out. Honor.
